I was going to say vegemite but I have actually heard of marmite and lettuce, so this sentence is mostly an excuse to giggle at the memory of a USan trying vegemite for the first time and spreading it thick on his bread like you would peanut butter.

Sandwiches with meat/salad-stuff were a minority of the sandwiches I ate when I was a kid.
